Ingredients You’ll Need

For the Peanut Butter Fudge:

• 1 cup unsalted butter
• 1 cup creamy peanut butter
• 1 teaspoon pure vanilla extract
• 4 cups powdered sugar, sifted
• 1/4 teaspoon salt, if using unsalted peanut butter and unsalted butter

Ingredient Notes:

Peanut Butter: Regular creamy peanut butter gives this recipe a smooth, consistent texture. Avoid natural peanut butter with separated oil because it can make the fudge too soft or oily.

Butter: Unsalted butter allows you to control the flavor. If you use salted butter, simply leave out the additional salt.

Powdered Sugar: This ingredient gives the fudge its structure and sweetness. Sifting it first helps prevent lumps and makes mixing easier.

Vanilla Extract: A little vanilla brings out the warm, nutty flavor of the peanut butter.

Salt: Just a small amount balances the sweetness and makes the peanut butter flavor stand out.

How to Make Peanut Butter Fudge

Step 1: Prepare the Pan

Line an 8-by-8-inch square baking pan with parchment paper, leaving a little extra hanging over two opposite sides. These edges will act as handles when you remove the finished fudge.

Lightly grease the parchment paper with butter or nonstick cooking spray if desired. Set the pan aside while you prepare the mixture.

Step 2: Melt the Butter and Peanut Butter

Place the butter and creamy peanut butter in a medium saucepan over low heat. Stir continuously with a silicone spatula or wooden spoon until both ingredients melt together into a smooth, creamy mixture.

Keep the heat low and avoid allowing the mixture to boil. Peanut butter can become oily or separate if overheated, so gentle melting is important for achieving the right consistency.

Once everything is completely combined, remove the saucepan from the heat.

Step 3: Add the Vanilla and Powdered Sugar

Stir the vanilla extract and salt into the warm peanut butter mixture.

Gradually add the sifted powdered sugar, about one cup at a time, stirring well after each addition. The mixture will become thicker as the sugar is incorporated.

Continue mixing until the fudge mixture is smooth, thick, and evenly combined. It should be firm enough to hold its shape but still soft enough to spread into the prepared pan.

If the mixture feels unusually dry or crumbly, make sure the powdered sugar was measured correctly before adding anything else.

Step 4: Transfer and Smooth the Fudge

Spoon the peanut butter mixture into the prepared baking pan.

Use a spatula or the back of a spoon to spread it evenly into the corners. Gently press the surface to remove large air pockets and create a smooth top.

For a pretty finish, you can sprinkle a few finely chopped peanuts over the surface while the mixture is still soft. Press them very lightly so they stick.

Step 5: Chill, Slice, and Serve

Place the pan in the refrigerator for approximately 2 hours, or until the fudge is completely firm.

Once set, lift the fudge out of the pan using the parchment paper handles. Place it on a cutting board and use a sharp knife to cut it into small squares.

For cleaner slices, warm the knife under hot water, wipe it completely dry, and cut straight down through the fudge. Repeat between cuts.

Arrange the squares on a serving plate and enjoy!

Helpful Cooking Notes

Use Low Heat: Always melt the butter and peanut butter gently. High heat can cause the fats to separate and affect the final texture.

Measure the Sugar Carefully: Too much powdered sugar can make the fudge dry and crumbly. Spoon it into the measuring cup and level it rather than packing it tightly.

Choose the Right Peanut Butter: Standard creamy peanut butter is the most reliable option for this recipe. Natural varieties can behave differently because their oil content and consistency vary.

Allow Enough Chilling Time: The fudge needs to become completely firm before cutting. If it feels soft in the center, return it to the refrigerator.

Use Parchment Paper: This makes removing the fudge much easier and helps keep the edges neat.

Cut Small Squares: Peanut butter fudge is naturally rich, so small pieces are perfect for dessert trays and sharing.

Delicious Peanut Butter Fudge Variations

Once you master the basic recipe, there are plenty of ways to give your homemade fudge a different flavor.

1. Chocolate Peanut Butter Fudge

Melt 1/2 cup of semisweet chocolate chips and spread the chocolate over the prepared peanut butter fudge. Refrigerate until both layers are firm, then cut into squares.

2. Chocolate Swirl Peanut Butter Fudge

Prepare the basic fudge and transfer it to the pan. Drizzle melted chocolate over the surface and gently swirl it with a toothpick or butter knife before chilling.

3. Crunchy Peanut Butter Fudge

Replace part of the creamy peanut butter with crunchy peanut butter, or fold in 1/3 cup of finely chopped roasted peanuts for extra texture.

4. Peanut Butter Pretzel Fudge

Stir 1/2 cup of crushed pretzels into the finished mixture before transferring it to the pan. The salty crunch pairs beautifully with the sweet peanut butter flavor.

5. Peanut Butter Chocolate Chip Fudge

Allow the mixture to cool slightly, then gently fold in 1/2 cup of mini chocolate chips. Cooling it first helps prevent the chocolate chips from melting completely.

6. Peanut Butter Marshmallow Fudge

Fold in 1 cup of mini marshmallows after the mixture has cooled slightly. The result is a softer, sweeter candy with little marshmallow pieces throughout.

What to Serve with Peanut Butter Fudge

Peanut butter fudge is delicious on its own, but it also makes a wonderful addition to a larger dessert spread.

• Christmas cookie trays: Serve it alongside sugar cookies, chocolate crinkle cookies, and shortbread.
• Holiday candy platters: Pair it with chocolate truffles, caramel candies, and homemade peanut clusters.
• Coffee and hot chocolate: A small square tastes wonderful with a warm cup of coffee or cocoa.
• Ice cream desserts: Chop a few pieces and sprinkle them over vanilla ice cream.
• Homemade gift boxes: Place individual squares in mini candy liners and arrange them in a decorative box.

For an attractive presentation, use a white ceramic platter or a wooden serving board. A few chopped peanuts sprinkled around the fudge make the platter look especially inviting.

Storage Instructions

At Room Temperature: Store the fudge in an airtight container in a cool room for up to 3 days. If your kitchen is warm, refrigeration is the better option.

In the Refrigerator: Place the squares in an airtight container, separating layers with parchment paper. Refrigerate for up to 2 weeks for the best quality.

In the Freezer: Arrange the pieces in a freezer-safe container with parchment paper between the layers. Freeze for up to 2 months.

To serve frozen fudge, transfer the desired amount to the refrigerator and allow it to thaw gradually. Keep the pieces covered while thawing to reduce condensation.

Frequently Asked Questions

Why is my peanut butter fudge too soft?

Fudge that is too soft may not have chilled long enough, or the ingredient proportions may be off. Make sure you use the full measured amount of powdered sugar and allow the fudge to become completely firm in the refrigerator before cutting.

Why did my peanut butter fudge turn out crumbly?

Crumbly fudge is often caused by too much powdered sugar or an incorrect measurement. It can also happen if the mixture becomes too dry while mixing. Measure the sugar carefully and add it gradually until the mixture is thick but still spreadable.

Can I make peanut butter fudge without a candy thermometer?

Yes! This recipe does not require a candy thermometer because the butter and peanut butter are simply melted together before the powdered sugar is added. There is no need to cook the mixture to a specific candy temperature.

Can I use crunchy peanut butter?

Yes. Crunchy peanut butter works well if you enjoy extra texture. Use the same quantity as the creamy peanut butter, choosing a regular commercial variety for the most consistent results.

Can I use natural peanut butter?

It is not recommended for this particular recipe. Natural peanut butter often separates, and its oil content can make the fudge greasy or too soft. Regular creamy peanut butter is a more dependable choice.

Can I make this fudge ahead of time?

Absolutely! This is a great make-ahead dessert. Prepare it a day or two before your event, cut it into squares, and store it in an airtight container in the refrigerator.

How do I get perfectly clean fudge squares?

Chill the fudge until firm. Use a sharp knife warmed under hot water and dried before cutting. Clean the blade between slices for neat, smooth edges.

Can I double this recipe?

Yes. Double all the ingredients and use a 9-by-13-inch baking pan. Make sure the mixture is spread evenly, and allow enough time for the larger batch to chill completely.

Is peanut butter fudge gluten-free?

The basic ingredients in this recipe are generally gluten-free, but always check the labels on your peanut butter, powdered sugar, vanilla extract, and other ingredients to confirm they meet your dietary needs. Avoid adding pretzels or other gluten-containing toppings.

Can I give peanut butter fudge as a homemade gift?

Yes! Cut the fudge into small squares and place each piece in a mini paper candy liner. Arrange the pieces in a decorative gift box or tin, keeping them cool during storage and transport. Clearly label the gift because peanut butter contains peanuts, a major food allergen.
